Brief summary
This clinical trial aims to evaluate the efficacy and safety of long needle and short needle in the treatment of internal hemorrhoids and rectal prolapse through CAES (Cap-assisted endoscopic sclerotherapy).
Detailed description
Traditional endoscopic sclerotherapy for internal hemorrhoids require retroflection of the endoscope. Retroflection of the endoscope has blind areas and affects the precise operation. And, short-needle injection can easily lead to artificial ulcer and secondary bleeding. CAES is a new, minimally invasive endoscopic technique for the treatment of internal hemorrhoids and rectal prolapse. CAES was performed based on the requirement of the cap, endoscope, disposable endoscopic long injection needle, enough insufflated air and sclerosing agent. It can accurately control the injection angle, direction and depth under direct vision, and avoid iatrogenic injury caused by ectopic injection to the greatest possible extent. To investigate the effect of long needle and short needle on the outcome of CAES, participants with internal hemorrhoids and rectal prolapse were randomly assigned to a long needle group and a short needle group using a prospective, randomized, controlled study at multiple centers in China. The efficacy, adverse events and satisfaction of the two groups were observed.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Recurrence rate | 24 weeks | Recurrence rate defined as the proportion of patients with recurrent hemorrhoids at 24 weeks post-CAES, as derived from patients' self-reported answer. Patients will be considered to have recurrent hemorrhoids when any of the following are recorded: (1)Unchanged or worse compared with before starting treatment at 24th week as reported by the patient, or (2) seeking repeat CAES treatment, alternative non-surgical/surgical treatments for internal hemorrhoids within 24weeks (except medication treatment), or (3) presence of any symptoms or events that strongly indicated recurrent hemorrhoids among patients not meeting (1) or (2). |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Symptoms of prolapse | 1day, 7days, 14days and 24 weeks | There are three degrees of prolapse: 1. No prolapse; 2: occasionally; 3: quite often. |
| Symptoms of anal pain | 1day, 7days, 14days and 24 weeks | NRS pain digital rating scale was adopted, that is, 0-10 was used to represent different degrees of pain, 0 was painless, and 10 was severe pain. 0 painless, 1-3 mild pain (pain does not affect sleep), 4-6 moderate pain, 7-9 severe pain (inability to fall asleep or waking up during sleep), 10 severe pain. |
| EQ-5D health scale scores | 24 weeks | Before CAES and after CAES, EQ-5D health scale scores were performed. |
| Symptoms of anal bleeding | 1day, 7days, 14days and 24 weeks | Bleeding is divided into three degrees: 1. No bleeding; 2. 2: occasionally; 3: quite often. |
| Satisfaction degree | 24 weeks | Number of satisfied participants |
| Symptom severity score | 1day and 24 weeks | five questions about hemorrhoidal symptoms (anal pain, prolapse, itching, soiling, and blood loss) will be self-assessed by patients by answering how often each symptom was encountered (never, sometimes, weekly, or daily). The score is the sum of the points from all five questions, ranging from 0 to 15 points, where an increase in number is an increase in symptom. |
| Adverse events and serious adverse events | 1day, 7days, 14days and 24 weeks | Adverse events included bleeding, anal pain, and dyspnea.Serious adverse events include serious complications directly or indirectly related to the operation, such as death, bleeding, perforation, etc. |
